RE: Trinity <span class=
UPDATE
Well - Last night was the first "fun Run" race at the local track, and here are some results that i have gathered.
This engine is just amazing. Set up for about 90-95% power, this engine just screamed. Its sound is soooo smooth, sounds like an F1 car. Max temp recorded with the body on in full race conditions was 231. Avg temp was 214. Smooth, consistant power band, and due to the short stroke bore, alot of power in the high RPM range. The modifcations by Rody increase the low end punch to big block standards. Consistant, reliable idle. No carb loading to speak of. For the entire night, through about 6 tanks of fuel - this engine never hiccuped, and never stalled once.
As for the chassis - amazing as well. Turn in is very predictable, and on power steering is crisp and sure. None of the on power oversteer that the ntc3 exibited. braking was secure and uneventful, hard acceleration was true and straight, with no pull.
This car is much easier to drive at the edge, and has a much tighter turn in and is able to power out of a turn slightly before the apex.
